eSIM for Indonesia — Instant 4G/5G Data Plans

Indonesia's mobile network is served by several main operators including Telkomsel, Indosat Ooredoo Hutchison, and XL Axiata. 4G LTE coverage is strong across Jakarta, Bali, Surabaya, Yogyakarta, and main tourist destinations on Java and Bali, with coverage extending to Lombok and the main Gili Islands. Outer islands including Flores, Sulawesi, Kalimantan, Papua, and the Maluku archipelago have coverage in main town centres but signal drops significantly in jungle, mountain, and remote coastal areas. Indonesia's vast archipelago of over 17,000 islands means connectivity varies enormously between well-visited tourist destinations and remote island communities. MobiSIM connects through supported local networks to deliver reliable data across Indonesia's main cities and tourist islands.

Install your MobiSIM eSIM before landing at Ngurah Rai International Airport in Bali or Soekarno-Hatta International Airport in Jakarta so you have data ready from arrival. Download offline maps for Bali, Lombok, the Gili Islands, Yogyakarta, and Komodo before travelling between islands, as ferry crossings and remote island areas can have no coverage. Keep your home SIM active for calls while MobiSIM handles your data. Ride-hailing apps including Gojek and Grab are essential for getting around Bali and Jakarta and require live data, making your eSIM immediately useful on arrival. If you are trekking to Mount Rinjani on Lombok, visiting Komodo National Park, or travelling to remote parts of Sulawesi or Papua, save all lodge contacts, route maps, and emergency numbers offline before departing the nearest major town.
